Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a liquid heating tube capable of heating a liquid by flowing the liquid through a heated tube, a heater using the heating tube, and the heating device. About sake ware.

[0002]

2. Description of the Related Art One of the heating methods for liquids such as water, sake, coffee, oil, and various solutions is to form a heater by incorporating an electric heating element in an insulating pipe and use the heater as a liquid filled in a container. There is a method of heating by immersing in a glass.

[0003]

However, this method is not suitable for heating a small amount of liquid because the heater needs to have a minimum amount of liquid soaked in the liquid, and the container for containing the liquid is also somewhat large. There's a problem.

In addition, it is necessary to prepare for heating the liquid to a predetermined temperature in advance as required, and further, since the heated liquid is stored in a container, there is a heat loss due to heat radiation during standby. Further, since a certain amount of heating time is required, there is also a problem that it cannot be made in a sudden need.

In view of the above problems, it is an object of the present invention to provide a liquid heating tube which can be miniaturized, has high thermal efficiency, and can obtain a liquid at a desired temperature immediately when necessary. And a sake brewing apparatus provided with the same.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, the outer peripheral surface of an electrically insulating tube is covered with a resistor closely adhered to the tube, and the outer peripheral surface of the tube is covered with the resistor. The liquid was heated by supplying heat to generate heat and flowing the liquid through a tube heated by the electric heating element.

As the tube material, ceramics made of alumina porcelain, zirconia porcelain, glass, crystallized glass and the like are preferable examples, but not limited thereto.

A method of arranging and covering the resistor in the longitudinal direction of the tube material and connecting electrodes at both ends of the tube material can be exemplified.

According to the present invention, the liquid can be obtained by immediately heating the liquid, and the required amount of liquid is heated, so that the heating tube can be downsized. Moreover, by selecting the diameter of the tube material and further by selecting the length of the insulating tube, the heating rate or the obtained liquid temperature can be selected.

According to the second aspect of the present invention, the outer peripheral surface of the electrically insulating tubular material is covered with a resistor printed thereon, and the resistor is energized to generate heat, and a liquid is caused to flow through the tubular material. Thus, the liquid was heated.
In printing, a general resistance paste is printed by a printing method.For example, after printing in a striped pattern in the length direction of the tube material, this is baked, and the resistor obtained by this is applied to both ends of the tube material with electrodes. What is necessary is just to connect.

When the tube diameter is small, a nickel-chrome ribbon wire may be tightly wound, or a heat-resistant shrink tube (for example, a tube made of polytetrafluoroethylene) may be covered. May be brought into close contact with the tube material by heat shrinking.

[0012] According to this, as compared with the mounting of a resistor such as a wire, a band or a foil, it can be easily performed in a printing operation and is suitable for a continuous operation and the like. In addition, since the adhesion of the resistor is ensured, the thermal efficiency when heating the tube material is improved.

According to the third aspect of the present invention, the first or second aspect is provided.
A liquid heater in which the liquid heating tubes described above are arranged in parallel, and the liquid supplied to the heater is branched and flowed to these tubes.

A large amount of liquid heat treatment can be performed,
Further, since the liquid is heated to a high heat, it is easy to secure a processing amount even when the liquid flows at a low speed.

In the case of a parallel pipe, if the difference in flow rate between the heating pipes is large, the liquid temperature is divided into a liquid temperature higher than a predetermined heating temperature and a liquid temperature lower than a predetermined heating temperature. By combining the liquids thus obtained, a predetermined temperature is obtained. Therefore, some liquids are heated above the predetermined temperature. However, when heated above the scheduled temperature, if the scheduled temperature is close to the boiling temperature, it will be boiled, and when heating coffee, for example, it may cause seizure in the heating tube, and furthermore, due to liquids In some cases, a temperature higher than the predetermined temperature may have an adverse effect such as a deterioration of the liquid.

In order to avoid such a problem, in the invention according to the fourth aspect, the liquid heating pipe according to the first or second aspect is connected in series to form a liquid heater. That is, since the outlet temperature of the series pipe is the location where the liquid temperature is the highest, setting the outlet temperature to the predetermined temperature can avoid the above-described problem.

In this case, the heating tube near the outlet is
By reducing the heating power compared to other heating tubes, it is also possible to take measures such as preventing burn-in. In order to reduce the power, the voltage to the heating tube or the resistance of the heating tube may be adjusted. This is a consideration for the following phenomena.

That is, in the serial piping, the temperature of the liquid is low at the entrance and high at the exit, so that the temperature of the heating tube itself is low at the entrance and high at the exit. As a result, the heating tube at the outlet is overheated, and the above-mentioned problems such as boiling and burning cannot be avoided. Even if the power supply of the entire heater is adjusted,
Since the room temperature itself fluctuates due to seasonal fluctuations, such factors may cause overheating in summer. On the other hand, if the heating power to the heating tube is not equalized, and the heating value is suppressed by setting the heating power in the vicinity of the outlet to be low, the heating tube in the vicinity of the outlet can be lowered as far as the liquid can be heated. In this way, the above-described problems can be avoided by realizing low-temperature heating near the outlet.

According to the fifth aspect of the present invention, a general sake brewing apparatus, that is, a supply unit for supplying sake, a heating unit for heating the supplied sake, and discharging the heated sake. The liquid heater according to claim 3 or 4 is used for a sake brewing apparatus having a discharge section for performing the heating. Specifically, the heating section is provided with the above-mentioned liquid heater, and the sake is heated.

According to this, the heat efficiency of the sake brewing apparatus is improved,
The sake liquor can be miniaturized and can be immediately warmed when needed.

When the above-mentioned heater is used, an electric current is applied to the wiring, and a desired liquid is sucked into the branch manifold at a predetermined flow rate. The inhaled liquid is branched and flowed to each heating tube, heated by flowing through the heated heating tube, collected by the collecting manifold, and then discharged from the outlet. Even if the heating temperature is slightly different for each heating tube, there is no problem because it is leveled during the assembling process.
